## Architecture

Jonathan Demo Test is a microservice designed with the following architecture:

- **Runtime**: Java Spring Boot
- **Deployment**: Humanitec Platform Orchestrator
- **CI/CD Pipeline**: Gitea Actions → Azure Container Registry (ACR) → Humanitec
- **Observability**: Prometheus metrics and Grafana dashboards for monitoring and alerting.

The service communicates with external resources defined in `score.yaml`, including database configurations for H2, MySQL, and PostgreSQL. It supports health check endpoints (`/health`) and metrics endpoints (`/metrics`) for operational insights.

## Configuration

| Configuration Option       | Description                                                                 |
|-----------------------------|-----------------------------------------------------------------------------|
| `spring.profiles.active`   | Specifies the active profile (`mysql`, `postgres`, or default `h2`).        |
| `jdbc:h2:mem:<uuid>`       | URL for accessing the in-memory H2 database.                                |
| `MYSQL_USER`, `MYSQL_PASSWORD`, `MYSQL_DATABASE` | Environment variables for MySQL configuration.       |
| `POSTGRES_USER`, `POSTGRES_PASSWORD`, `POSTGRES_DB` | Environment variables for PostgreSQL configuration.|
